Joyee Cheung bb98b38735 [ic] handle access check for private names
Previously the LookupIterator ignores private symbols
(including private names) for the access check. This patch
removes these exceptions so that they are always checked.

Drive-by: removes the unused should_throw parameter in
Runtime::DefineObjectOwnProperty()
